Bosch Premium Oxygen Sensor Sensor

The Bosch Premium Oxygen Sensor (also called an O2 sensor or lambda sensor) measures the amount of oxygen in the exhaust stream. It sends that data to the engine control unit, which uses it to fine-tune the air-fuel mixture. Accurate readings help the engine run efficiently, keep emissions low, and support good fuel economy and drivability.

Key Features:

• Made by Bosch, which invented the automotive oxygen sensor and supplies many vehicle manufacturers
• Designed to give accurate, fast signal response for precise air-fuel ratio control
• Built to withstand the high heat, vibration, and contaminants found in exhaust systems
• Pre-installed wiring and connector designed for plug-and-play installation
• Helps the engine maintain proper combustion, supports catalytic converter efficiency, and helps prevent check engine light faults related to sensor failure

A worn or failing oxygen sensor can cause poor fuel economy, rough idling, increased emissions, and a lit check engine light. Replacing it with a Bosch Premium oxygen sensor helps restore proper engine management performance. Choose the child item that matches your application's sensor position and connector type.
